HASP-LOCK.

SPECIFICATION forming part of Letters Patent No. 362,986, dated May 17, 1887.

.\ pplicatifui filed March T, 1887.

To all whom, it may concern:

Be it known that I, FRANK XV. MIX, of New Britain, in the county of Hartford and State 0f Connecticut, have invented certain new and useful Improvements in Hasp-Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My'invention relates to an improvementI in hasp-locks, and particularly to a style adapted for use on trunks or boxes having hinged lids.

rlhe object of my present invention is to provide a hasp-lock that is of neat shapely form, light, strong, durable, and reliable in its wearing parts, and that can be rapidly produced from sheet metal by cutting and forming dies.

A further object is to so construct a hasplock for trunks or boxes that it can be secured to the body and lid of these receptacles without cutting the body of the trunk or box to receive the lockiligplate.

Vith these objects. in View my invention consists in certain features of construction and combination of parts, that will be hereinafter described, and pointed ont in the claims.

Referring to the drawings making a part of this specification, Figure l is a front elevation of the hasp, its attached lock, and the locking-plate. Fig. 2 is a side elevation, in section, of the lock, hasp, and lockiiigplate. Fig. 3 shows a modified form of locking attachment to secure the hasp-lock and locking-plate in closed adjustment. Fig. 4 is a front View of the locking-plate used with the lock shown in Fig. Fig. 5 is a side elevation, in section, of the modified form of lock and hasp-plate and locking-plate shown in Fig. 3.

A represents the hasp, the upper part, A', of which is adapted to be secured to the lid of a trunk or box. rlhe hinge is of a novel form, having an integral pintle rolled into a cylinder from the sheet-metal material of which the hasp-plate is constructed. A separate application for patent on this specific detail of the hasp is now pending, and therefore need not be further described in this connection. The pendent hasp-plate A2 is made of a curvilinear form to receive the cap-plate B, which covers the locking mechanism. It will be noticed that the lock mechanism is Serial No. 230,015. (No model.)

placed directly upon the outer face of this pendent hasp-plate A2, to which the cover or cap-plate is secured by rivets or other suitable method.

The lockingplate C is preferably cutout of sheet metal, having a raised rib or projection, I), stamped up by forming-dies upon its outer surface. This rib is arranged in the arc of a circle which extends from points a a near the upper edge of the locking-plate C, and is of such a relative width or diameter on its interior edge that it will receive and neatly fit the curved edge of the pendent hasp-plase A2, together with thc attached cap-plate B, as shown in Fig. l.

A loop, b, is rigidly secured to the locking plate C, preferably at a point central between the terminations a a ofthe rib D. This loop is made to neatly fit a slot, D', whiehis cntinthe pendent hasp-plate A2, and penetrate the eapplate to engage a sliding bolt of the locking mechanism when the same is operated by a proper key.

\Vhen the loop and bolt are in close adjustment to hold the pendent hasp-platc A2 and its attached lock together, the strain upon the hasp-plate will partially be received by the abutment of the rib upon the edge of thehaspplate, and also by the loop which is attached to the pendent hasp-plate, so that this strain will not affect injuriously the bolt or other interior locking mechanism of the lock, the bolt having sufficient clearance edgewise in the loop to insure this result.

In the modified form of hasp-loek shown in Figs. 3 and t the construction ofthe pendent hasp -plate A2, which receives the locking mechanism, and the cap-plate B is similar to that shown in Figs. l. and 2, and the locking-plates C are identical in form, each having a raised rib struck up on a sheet-metal blank to form a border for the cap-plate B.

The upper portion, A', of the hasp that is to be secured by screws or nails to the trunklid is provided with proper perforations for such a purpose, and a plate-spring, c, is secured to the rear Vface of this hasp-plate to throw out thependent portion when the same is released from locking-contact with the lock-V ing-plate C.

rIhe lockingplate C, Figs. 3

and 4, is pro- IOC) rigidly to a bolt that is connected 'to the lockmechanism and is adapted to be turned to secure the projections on this oval lug to the rear surface of the locking-plate C. The integrally-formed flange e, that is made to project from the rear surface of the pendent haspplate A2, (see Fig. 5,) is made of such a relative diameter to the width of the center of the oval hole in the locking-plate C that it will enter and t neatly, so that the oval locking-lug E, which has a revoluble bearing on the face or edge of this annular fiange e, will hold the pendent haspplate' A2 and locking-plate C in close adjustment when the bolt which ear-ries the locking-lug E is partly rotated, and it will be noticed that the engagement thus effected will transfer any bursting strain imposed upon the hasp-plate A2 to the annular flange e and the engaged edge of the locking-plate C.

The locking-plates C are furnished with ears d, that are perforated to permit the insertion of screws, rivets, or securing-nails. These plates C may be made of an ornamental form, as shown, or a plain rectangular shape may be given to them, if preferred.

It will be seen that the locking-plates C and the opposed portion of the pendenthaspplate A2 (shown in Fig. 2) have dat adjacent surfaces; also, that the rear face of the lockingplate C is plain, or without rearward projections that would require a cavity or hole made into or through the wall of the trunk to receive it.

The provision just named is an important feature of the present invention, as it affords a reliable lock that can be used on trunks having very thin walls without cutting into or through the same, and thus present a neat l finish upon the interior as well as on the outside cf the trunk or boX to which alock of this make is attached.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. Ina hasp-lock, the combination, with a locking-plate having a rib projecting from its front face, of a pendent hasp-plate, the lower edge of which is adapted to conform in shape to the space inclosed by the rib, and a lock secured to the front face of the pendent haspplate, substantially as set forth. j

2. In a hasp-lock, the combination, with a pendent hasp-plate having an integral annular fiange formed on its rear face, a lock secured to its front face, and a cap-plate to cover the lock mechanism, of a slotted locking-plate which permits the locking-lugs of the lockte pass through it and engage its-rear surface, the annular flange of the hasp-plate havlng bearing-contact with' the oval slot in the locking-plate to prevent a bursting strain from being transmitted to the locking mechanism of the lock, substantially as set forth.

3. Ina hasp-lock, the combination, with a pendent hasp-plate having an integral annular iiange made to project from its rear face, a lock secured to its front face, and a cap-plate to cover the lock mechanism, of a locking'- plate that has a rib raised upon its front face, which forms a lateral abutment forM the lockcover, the locking-plate being perforated to allow the locking-lugs of the lock to pass through it and engage its' rear surface, and the annularange of the hasp-plate having bearingcontact with the edge of oval slot in the locking-plate when the hasp and locking plates are in closed adjustment, substantially as set forth.

In testimonyv whereof I have signed this specification in the presence of two subscribing witnesses.

FRANK W. MIX.
